Background of the invention

This invention relates to compositions elastomeric and composition manufacturing procedures elastomeric More specifically, it refers to compositions thermoplastic-elastomeric and procedural to make compositions thermoplastic-elastomeric.

Usually, a single material cannot provide all the desired properties of an article of manufacturing. Therefore, a single chemical does not will provide an item that simultaneously has a high strength and elasticity like rubber, or hardness and high rigidity, on the one hand, and high traction on the other.

When you have to face a challenge of this type, the most frequent solution is to combine two materials  in order to provide a new material that has the necessary features. Previously, elastomers (rubbers) had been used in combination with thermoplastics for provide elastic and high strength compounds. All the approaches adopted to date involve the formation of layers of the two different materials, the layers being adhered each other either by an adhesive or by a joint superficial.

For example, U.S. Patent No. 4,835,063 to Jadamuss et al . discloses composite parts comprising a thermoplastic layer containing polyphenylene ether surrounded by a layer of styrene-butadiene rubber (SBR, Styrene-Butadiene Rubber ) or styrene-butadiene-styrene (SBS, Styrene-Butadiene-Styrene ) which is , in turn, surrounded by a layer of natural rubber. There may be an optional intermediate layer comprising a mixture of powder SBR and filler between the SBR layer and the natural rubber layer.

U.S. Patent No. 5,153,076 to Jadamus et al . discloses a chemical bonding procedure between polyphenylene ether containing a material and synthetic rubber by covulcanization. The chemical bonding is made between the surfaces of the two materials, and is achieved by contacting the two materials and subjecting both to vulcanization conditions.

U.S. Patent No. 5,332,621 to Schmidt et al . discloses a composite article comprising latex foam intimately bonded to a thermoplastic molded portion containing polyphenylene ether. Once again the elastomeric material and the thermoplastic material are present in different layers.

The document EP-A-0562179 reveals a composition of electroconductive resin comprising 100 parts by weight of a polyphenylene ether, from 1 to 50 parts by weight of a compound of diamide and 5 to 35 parts by weight of a carbon black having an absorption of butyl phthalate of 70 ml / 100 mg or greater. This composition is excellent in electroconductivity, processability and thermal resistance

The document EP-A-0491187 reveals mixtures extruded molten rubber based on dienes and ether of pre-extruded polyphenylene, or mixtures of themselves with an effective amount of a stabilizer such as a hindered phenol or a hindered phenol / metal deactivator. The resulting polyphenylene ether composition can be Extruded in greater depth with an organic matrix material polymeric, such as a polyamide or a polyetherimide. When are molded, it has been discovered that ether compositions of Polyphenylene is overcome the loss of impact resistance before thermal aging or recycling.

The document GB-A-1330947 reveals a procedure to prepare a powder composition comprising an ether of polyphenylene and a rubber, comprising the steps of dissolving a polyphenylene ether and solvate a rubber in a solvent medium to form a solution of said polyphenylene ether and said solvated rubber, and precipitate said polyphenylene ether and said rubber as a homogeneous mixture of finely ground powders by mixing said solution with a non-solvent substance for said polyphenylene ether and said rubber. The compositions have a better impact resistance due to the increase in rubber content

The document US-A-3383340 reveals a composition comprising an elastomer selected from the group constituted  for natural rubber and synthetic rubber, and for 10 to 150 parts in weight per 100 rubber parts of a reinforcing filler particulate having a particle size of 0.1 to 200 micrometers, said filling being a polyphenylene oxide.

As can be clearly seen from the Previous patents, to date, the approach to combine elastomers and thermoplastics has focused on composite materials formed by layers of each material that are joined superficially with each other. This is due to differences. substantial in processability as well as compatibility limited between poly (arylene ether) and rubber. Approaches of layered compounds do not provide a property profile uniform across the material, which limits the applicability of these materials in situations such as the surfaces of rolling, in which the elasticity and high strength are important, especially at high temperatures.

Efforts continue to improve materials used on rolling surfaces. The questions key are wear resistance, adhesion (traction) in Wet and rolling resistance. A rolling surface With excellent properties in all three fields you will have a long wear resistance and will improve both safety and fuel consumption. In general, it is believed that a temperature of transition of the highest vitreous state (Tv) corresponds to a better wet grip and wear resistance, although it can also result in increased resistance to swinging. The tan delta factor (tan?), The loss factor viscoelastic (internal friction) of a material measured with dynamic mechanical testers, at low temperatures (usually at 0 ° C), should be elevated to improve wet adhesion. He tan? at high temperatures (normally, 75-80ºC) should be low to improve the rolling resistance Current tread surfaces they have values so δ that vary from 0.16 to 0.20 at 75 ° C.

Therefore, there is still a need in the technique by compositions thermoplastic-elastomeric elastic and with high resistance, especially at elevated temperatures, and by manufacturing procedures

Previously, rubber and rubber could not be successfully combined poly (arylene ether) due to the need to process the poly (arylene ether) at temperatures exceeding the point of rubber combustion Contrary to perception generally extended in the art, it is possible to produce compositions of poly (arylene ether) and copolymer of styrene-butadiene by, for example, the combination of a low viscosity poly (arylene ether) intrinsic (i.e., a VI of approximately 0.35 dl / g or less) with a styrene-butadiene copolymer at a higher temperature of the combustion temperature of the copolymer. The resulting composition has a better Tan? Value at low temperature (eg, 0 ° C), with a Tan δ similar to high temperatures (eg, 80 ° C). The additional advantages of These compositions include, better wet adhesion, rolling resistance and wear resistance, among others.

Although they have been shown and described the preferred embodiments, several modifications can be made and substitutions thereof without departing from the spirit or the scope of the invention. Therefore, it should be understood that the The present invention has been described by way of illustration and without limitations
